Concrete block wall with air in cavities = R 2.0 . Concrete block wall with Perlite in cavities = R 2.9 . The reason that it is important to make a good estimate for the current R value for uninsulated spaces is that small changes in R values result in large changes in heat loss when the total R value is low.
